Descrição geral
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.
Download your certificate at: http://www.sigma-aldrich.com2,4,5-T is a synthetic auxin that belongs to the family of chlorinated acid herbicides, used to defoliate broad-leafed plants.
As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, 2,4,5-T is not approved for use in the European Union. But a default maximum residue limit (MRL) of 0.01 mg/kg is applicable for the presence of 2,4,5-T (taken as a sum of 2,4,5-T, its salts, and esters) in products of plant origin, in accordance with Regulation (EC) No. 2015/868.
